This Eskilstunasteel Gensco chisel looks ordinary from a distance.
However a closer look reveals that it has a “1030 – 3/4” stamped on the front of the blade. 1030 was a model number used by E.A. Berg and Jernbolaget for tanged, beveled, butt chisels. Eskilstunasteel did not use that model number for their chisels.
Wait a minute. The back of the blade has a Jernbolaget blade stamp on it. We’ve seen that before on a Gensco brand chisel. This was done after Bahco bought out Jernbolaget, Eskilstunasteel, and Berg circa 1959 … a perfect time to make some Frankenchisels. You can read more on this here Gensco Chisels . (Go to the bottom of that article, before the comments.)
I probably would not have posted anything about the chisel above after already writing about the Bahco-Jernbolaget-Gensco merger in an earlier post. However, I found the front blade stamp interesting. First, the chisels I wrote about previously had everything etched on their back (see below). And second, the chisel above does not have a metric measurement stamped on the front of the blade. Although interesting (to me), I cannot imagine how it would be important in any way.
Randall Nelson sent me some photos of two interesting Berg chisels. These chisels came inside Jernbolaget packaging as shown below. (You can see “JERNBOLAGET” written on the right corner of the wrapper.)
Here is the blade stamp for the 1/2″ chisel, reading “1026 – 1/2”. 1026 is the Berg and Jernbolaget model number for their tanged and beveled cabinet or firmer chisels.
Here is the Berg logo stamped on the back of the chisel. It reads “EA BERG” | “ESKILSTUNA” and has a modern version of the Berg shark stamped below the text.
Here’s a closer look at the chisel wrapper for the 5/8″ Berg chisel. The Jernboalget logo ( the “E”, Crown, and Anchor) shows up clearly on the wrapper.
Again, the best explanation for this mix of brands is that it took place after Bahco bought out Berg and Jernbolaget circa 1959. I believe that these chisels were made and sold in the early 1960s.
Note that the above chisels are unusual in that they have a socket-style base and a squared off tang. These hybrid Berg chisels are not common. For more information on them click Berg Socket-Ferrule Chisels .
